Mono Propylene Glycol
Kufotokozera Zamalonda
Ndi madzi opanda mtundu okhala ndi kukhuthala kokhazikika komanso kuyamwa bwino kwamadzi.
Ndi pafupifupi yopanda fungo, yosapsa ndi poizoni pang'ono.Mamolekyu ake ndi 76.09.Kukhuthala kwake (20oC), kutentha kwapadera (20oC) ndi kutentha kobisika kwa vaporization (101.3kpa) ndi 60.5mpa.s, 2.49KJ/ (kg. oC) ndi 711KJ/kg.
Ikhoza kusakanikirana ndi kuthetsedwa ndi mowa, madzi ndi ma organic agents osiyanasiyana.
Propylene Glycol ndi zopangira pokonzekera unsaturated polyester resin, plasticizer, pamwamba yogwira agent, emulsifying agent ndi demulsifying agent.
Itha kugwiritsidwanso ntchito ngati inhibitor ya nkhungu, antiseptic pazipatso, ice inhibitor ndi kuteteza chinyezi kufodya.

Kugwiritsa ntchito
(1) Propylene glycol imagwiritsidwa ntchito ngati zida zopangira utomoni, mapulasitiki, ma surfactants, emulsifiers ndi demulsifiers, komanso antifreeze ndi zonyamula kutentha.
(2) Propylene glycol amagwiritsidwa ntchito ngati mpweya chromatography stationary madzi, zosungunulira, antifreeze, plasticizer ndi dehydrating wothandizira.
(3) Propylene glycol zimagwiritsa ntchito zosungunulira m'zigawo zosiyanasiyana zonunkhira, inki, preservatives, vanila nyemba, wokazinga khofi granule, kukoma zachilengedwe ndi zina zotero.Wofewetsa komanso wofewetsa wa maswiti, mkate, nyama zopakidwa, tchizi, ndi zina.
(4) Itha kugwiritsidwanso ntchito ngati anti - mildew agent pazakudya zam'madzi ndi kudzaza pachimake.Onjezani 0.006% ku mkaka wa soya, womwe ungapangitse kukoma kwake kusasinthike mukatenthetsa, ndikupanga mafuta opaka nyemba zoyera komanso zonyezimira.
